I have a monorepo stup using bun. I am having issues deploying it using railway. Here is my current folder structure:
.
└── repo/
├── apps/
│ ├── api/
│ │ └── package.json (B)
│ ├── ui/
│ │ └── package.json (C)
│ ├── db/
│ │ └── package.json (D)
│ └── app/
│ └── package.json (E)
├── packages/
│ └── contracts/
│ └── package.json (F)
└── package.json (A)I keep getting this error
╭────────────────╮
Railpack 0.9.2
╰────────────────╯
↳ Detected Node
↳ Using bun package manager
↳ Found workspace with 5 packages
No start command was found.
To configure your start command, Railpack will check:
1. A "start" script in your package.json:
"scripts": {
"start": "node index.js"
}
2. A "main" field in your package.json pointing to your entry file:
"main": "src/server.js"
3. An index.js or index.ts file in your project root
If you have a static site, you can set the RAILPACK_SPA_OUTPUT_DIR environment variable containing the directory of your built static files.I currently have the following in Watch Paths
- /apps/api/**
- /apps/ui/**
Root Directory is set to /
Do i need a custom railway.json for api and ui?
I only want to deploy the ui and api and then do a migration to a database in railway

you might need a custom railway.json.
This tool might help with making one: https://railpack.crisog.com
https://docs.railway.com/guides/monorepo#automatic-import-for-javascript-monorepos
mentions that it will automatically detect the services in the monorepo, but i only see 1 service which is the monorepo, it's not splitting each service separately.
yes, therefore, you might need a custom railway.json.

If you set up a public repo with an minimal example setup, I can help debugging this issue
does not answer my question. Do i need a seperate railway.json for each? where do i put it under each package? if so then the monorepo will not be able to install packages that are dependent from other packages

here is a minimal repo

Hi.
You need to create two services. Set the root directory of one to apps/ui, and the other to apps/api. Make sure you correctly configure the endpoints. This should not and I believe cannot be done with one service.

Alright. I'm going to send in a PR.
For one service, your API, you'll set the root directory to be nothing. Set the start command to be bun start:api.
For your UI, set the root directory to be apps/ui. The rest should be automatic for that.
Beautiful, the api seems to be working, but the UI still returns the same error
bun install --frozen-lockfile
bun install v1.3.1 (89fa0f34)

Hmm. I didn't see usage of those APIs, but I guess they're needed. Going to look again, brb.
They're under the
"@railway-test/contracts": "workspace:*" package, elysia is used in the catalog

Almost there...

Here we go.
Set your UI service back to no root directory.
Scroll to "Custom Build Command" and set it to cd apps/ui && bun vite build
Add a variable called RAILPACK_SPA_OUTPUT_DIR and set it to apps/ui/dist

I'm also going to submit a PR that allows you to connect these two services. Right now you're just looking on localhost.

Are you referring to a specific part of that? There's a lot there

I can help you implement a Dockerfile which I believe will do all of the compilation in one shot, and won't require much of any setup at all.

But smaller size doesn't matter on Railway, and I can't imagine the memory usage will differ that much either
i currently have this build script under apps/api
"build": "NODE_ENV=production bun build --compile --minify --target=bun-linux-x64 --outfile dist/server ./src/index.ts"
which builds a single executable, how can i make the railway service run that executable

You'll need to change three things:
- Your build command (in Railway):
bun --filter @railway-test/api build - Your start command (in Railway):
./apps/api/dist/server.

I'll try that on my fork

Oh shoot, this is not for the UI
